Preparation of High Antibacterial, Easy Coating, and Easy Cleaning Pea Protein Isolate/Zein-Carboxymethyl Cellulose Composite Coating Material and Its Preservation Application

Abstract

This paper fabricated a new kind of pea protein isolate/Zein-carboxymethyl cellulose composite coating material with Pickering emulsion morphology through the solution blending method. The pea protein isolate/Zein-carboxymethyl cellulose composite coating material exhibited high antibacterial properties, delayed spoilage, and easy-to-coat and easy-to-clean properties. In addition, the ultraviolet shielding properties, hydrophilicity and hydrophobicity, antibacterial properties, antioxidant properties, and preservation properties of fruits were studied. This pea protein isolate/Zein-carboxymethyl cellulose composite coating material avoided the volatilization of clove essential oil and achieved long-term antibacterial properties, and it is fit for the preservation material field.
